I’d been looking at the “you need to upgrade your WordPress software” warning for a few weeks, wondering whether the fixed vulnerabilities existed in 2.7.x, when this broke (Scoble was on 2.7 and got hit, so the vulnerability goes back at least that far), and I finally bit the bullet. It’s harder than it ought to be because my hosting provider doesn’t let me allocate as much memory as the automatic WP upgrade needs, but aside from the natural pain of “I’ve never done this before, and I really don’t want to break my blog”-inspired double-checking of everything, it wasn’t so bad. So if you’re running your own WordPress blog, please upgrade to 2.8.4 now.
